The Oort Cloud isn't that close, but it's significantly too close for comfort to know that a binary star system clipped it (well within Sol’s tidal radius) around 70 kyr ago.

And here's proof I can't draw, but better than the even less I couldn't draw last time.

🌌 Far beyond the last bright planet, the solar system softens into an inferred halo where icy bodies drift in deep quiet. Long-period comets arrive like messages from that distant frontier, written in motion rather than light.

🌠 Some frontiers reveal themselves through patience and wonder.

Fascinating: ESA is now preparing the Comet Interceptor mission
The spacecraft will be launched in 2029 into a parking orbit, lying in wait for a suitable target – a pristine comet from the Oort Cloud, or, unlikely but highly appealing, an interstellar object.

Tohle je fasicnující - naprostou náhodou bylo díky vizualizaci reálných dat zjištěno, že Oortův oblak má ve skutečnosti tvar spirály (něco jako minigalaxie kolem Sluneční soustavy!)

If my simple mathematical model holds, a comet in the Oort cloud who runs a 1.2 million year word-of-mouth campaign against the inevitable incursion of the star Gliese 710 will need to personally convince 42 comets if they want to get 5% of the cloud’s 20 trillion space rocks to sign their petition.

The vastness of Space, the Oort cloud and Voyager🧪
“Voyager 1, the fastest and farthest of the interplanetary space probes currently leaving the Solar System, will reach the Oort cloud in about 300 years and would take about 30,000 years to pass through it.”

#NASA’s #Webb #Telescope Finds Water, and a New Mystery
#JWST's near-infrared camera detected first known instance of #water vapor around a #comet in main #asteroid belt, also known as a main belt comet. Scientists had thought comets could preserve water ice so relatively close to the Sun, but didn't have firm evidence until now. They generally expected comets to sit in the #KuiperBelt or #OortCloud, both of which are far enough away from the Sun that ice could last.

When the title of a paper - "Direct measurement of decimetre-sized rocky material in the Oort cloud" - is obviously too obvious ... and the journal that published it puts it on the cover and gets the astronomy dead wrong: https://twitter.com/meteordoc/status/1639297365474529281. Anyway, the paper as such is quite interesting and you can read it open access at https://arxiv.org/abs/2212.06812 #meteors #OortCloud #SolarSystem

Why Does The Universe Exist? With Neil deGrasse Tyson -
"Biver said the #comet was believed to have come from the #OortCloud, a theorized vast sphere surrounding the Solar System that is home to mysterious icy objects.
The last time the comet passed Earth was during the #UpperPaleolithic period, when #Neanderthals still roamed Earth."
